Hi, Will the markers receive a black and white copy of our exam scripts? I am wondering if it is okay to represent different series of data using different colours in charts? In this exam, the examiner will only receive our Word document without the Excel file where the chart is originally created. If they will be all in grey scale, the examiners can't easily identify the different data, does that mean it will be safer to use different line patterns although it costs time to format them?
